CONTRACT RELEASE C20-004
NASA Awards Launch Services Contract for Earth Science Mission

NASA has selected SpaceX of Hawthorne, California, to provide launch services for the agency’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.

The total cost for NASA to launch PACE is approximately $80.4 million, which includes the launch service and other mission related costs. The PACE mission currently is targeted to launch in December 2022 on a Falcon 9 Full Thrust rocket from Cape Canaveral Air Force Station in Florida.

The PACE mission represents the nation’s next great investment in understanding and protecting our home planet. The mission will provide global ocean color, cloud, and aerosol data that will provide unprecedented insights into oceanographic and atmospheric responses to Earth’s changing climate. PACE will help scientists investigate the diversity of organisms fueling marine food webs and the U.S. economy, and deliver advanced data products to reduce uncertainties in global climate models and improve our interdisciplinary understanding of the Earth system.

NASA’s Launch Services Program at the agency’s Kennedy Space Center in Florida will manage the SpaceX launch service. The PACE mission is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the agency’s Science Mission Directorate in Washington.

SpaceX Statement:

NASA’s Launch Services Program (LSP) has awarded SpaceX launch of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission on a flight-proven Falcon 9. Additional information on the award can be found here, and the following statement can be attributed to SpaceX President and Chief Operating Officer Gwynne Shotwell.

“SpaceX is honored to continue supporting NASA’s critical scientific observational missions by launching PACE, which will help humanity better understand, protect, and preserve our planet.”

SpaceX has completed 82 Falcon 9 and Falcon Heavy missions to-date, including two for NASA’s LSP – Jason-3 and TESS. In addition to PACE, SpaceX’s future launch manifest includes NASA’s LSP missions SWOT, Sentinel-6A, DART, and IXPE.

The total cost for NASA to launch PACE is approximately $80.4 million, which includes the launch service and other mission related costs.

Even with "other mission related costs", I would imagine that SpaceX will make a large profit on this flight even though I also imagine that they had the lowest bid. Putting a 1700 kg satellite into a sun-synchronous orbit, even from Canveral (edit; OK, that might be hard; certainly it'd be easy from Vandenberg) seems like a softball for them and (I'm guessing) it will be a return-to-launch-site mission.

Not that I'm complaining, even as a US taxpayer. I'd like to see beyond earth orbit human exploration and IMO I get better bang-for-the buck having the US Govt give money straight to SpaceX, than spending it themselves trying to accomplish lesser and more expensive BEO objectives. Such is the world we live in....

This was in the 2019 GAO assessment of major NASA projects:
Quote
Launch
The PACE project is continuing to pursue a shared ride agreement with the Air Force, which could help to mitigate a launch vehicle risk that the project is tracking. The launch vehicle cost remains one of the project’s top risks, which could cause the project to exceed the $705 million allocated to the project or have to reduce its science capabilities. The project has $105 million budgeted toward the launch vehicle, but officials say a rideshare would significantly reduce costs. NASA and the Air Force have determined there is a path for a shared launch vehicle procurement, but no partner mission has been identified. The project currently plans to begin the procurement process in early 2019 and award the launch vehicle contract in November 2019.

Vega-C hasn't flown yet and thus would not be certified by LSP which is a requirement to bid. Vega doesn't have the performance for this mission, and so even without the political issues, Ariane could not have won this mission with Vega.

The competition in this performance bracket among potentially certifiable vehicles is between Antares, Euro Soyuz, F9R, and Atlas V. Antares is around $80 to $85M, and I think Euro Soyuz is in the same price bracket. Atlas V 401 is at least $110M plus more for NASA-specific services.

So F9R even at $80M was probably the cheapest option, even considering Ariane's current vehicles.

I don't think it's silly. NASA should be able to certify European LVs, and source bids for launches. More competition is better for everyone.

I think F9R would have beat Vega-C in a bid anyway. We know it's already beating Pegasus, and that it has definite potential to move further down the market.

That would be silly, because it would be the equivalent of saying it could have launched on a Falcon 9 for $50 million US.  Extra services required by NASA (and USAF) are a real thing and are expensive.  It's also the total cost of the launch, and in the past we've seen that not all the money is going to SpaceX as there is e.g. payload processing to consider.  (There's also the possibility that a future ride share booking will reduce the impact on NASA, but there is no news of such a rideshare at this time).

Separately, is this the first time a NASA LSP flight booked on a Falcon 9 will use a flight-proven core?  I don't remember any others, but I might have missed it.

IXPE is launching for $42M, and includes 5 mission-specific services. I don't know how many services NASA bought for PACE, but I'm guessing probably not an additional ~100% of the base launch cost.

PACE might require a ASDS recovery which would be an upcharge over IXPE which can probably go RTLS, But even that probably isn't enough to explain much of the difference.

I think most of the price difference from IXPE is SpaceX knowing that they only had to beat Antares and Atlas at $85-$110+ million, instead of having to beat Pegasus at $45-$55 million.

IXPE
I haven't looked at LSP certification stuff in a long time, do you know (or does anyone else know) if a flight-proven booster is in a different (higher-risk) category than a new booster?

(Since SpaceX keeps picking up Delta II/Pegasus class launches but can't seem to secure higher-priced missions, I'm not sure we could tell the difference right now.  I went to look at the graphic they used to have with future missions and what LV they were assigned to but I can't find that anymore either.)

Maybe, but I could swear I read somewhere that IXPC was a rideshare, but my googling has shown just speculation that it will be.

Regarding the services question, services are not equal for spacecraft.  Unfortunately we rarely get that kind of information as to what the bid price was for the base launcher and how much goes to services (or even how much goes to e.g. payload processing done by a different company).  So it's hard to compare across missions.  I will admit that claiming they are always expensive is not well supported, we just don't know in this case.

SpaceX might be able, if they want, to sell some excess capacity on the IXPE launch to a rideshare, but equatorial LEO is an oddball orbit so I doubt they will find one that is ready to go and can pay enough to be worth the hassle.

I find it more odd that SSO launches like PACE aren't more frequently rideshares. There should be a much larger market.

The PACE contract was just signed for a 2022 launch, and the PACE folks were previously openly hoping for a rideshare to reduce cost.  I think there's an excellent chance it will end up having co-passengers by the time it flies.

Not that Rik was really refuting the value of Falcon 9, but we know from IXPE that the price of Falcon 9 to NASA is around $50M. Therefore there are about $30 of “other services” that would have to be added to competing rockets’ “list price”.


To beat Falcon 9 a similar sized rocket needs something other than price.

I could just as well replaced Vega-C with PSLV or Soyuz 2.1v. All US commercial smallsats had to go outside of the US for an affordable launch. Hopefully Rocketlabs, Firefly, Virgin Orbital and Astra Space can change this.
Why can't PACE launch for 5000 $/kg or $8,5mln + 30mln services?
It's a plain SSO launch. If NASA permits SpaceX to sell the residual capacity under their smallsat program, the main satellite should have roughly the same $/kg.
$50mln/1700kg gives ~29,4K $/kg.
That's nearly six times the smallsat program fare.

Could this possibly have something to do with launching from Vandenberg instead of the East coast?
[No, Multiple sources state it will launch from Cape Canaveral.]

In Europe launch orders are delayed so Vega-C and Ariane 6 can prove themselves with their maiden launch. (Sentinel C & D's) Why doesn't this happen in the US?
This is more related to the IXPE launch contract. AFAIK that should have been a Venture class payload.

But this is pennies if you compare it with SLS and Orion. I'm glad with how ESA / Europe deal's with their launchers if I compare it to the US.

I'm not aware of any US launch vehicles nearing the end of development that would be suitable for this payload?  If NASA is paying for the launch then it's going on a US vehicle.  If ESA or JAXA were partnering on the mission then there might be other options like Vega-C or H-3.

If Firefly's Beta is ever built its targeting 3,000kg to SSO and 4,000kg to leo. Of course it's a long ways off as they still have to get Alpha flying successfully. I think its about the only thing going after that payload class anytime soon.

From annual GAO report:
Quote
Cost and Schedule Status

The PACE project entered the implementation phase and
formally established its cost and schedule baselines in
August 2019. The project set a baseline lifecycle cost
of $889.7 million and a launch date of January 2024,
which is $39.7 million above the top-end of the project’s
preliminary cost estimate of $850 million and 9 months
later than its preliminary schedule estimate of April 2023.
The project continues to be cost-capped but NASA added
$33.8 million to the project’s baseline to account for a
2.5-month delay from the fiscal year 2019 government
shutdown and interest payments on outstanding contractor
invoices. For example, NASA reported that the shutdown
delayed contractor deliverables because the project
could not provide direction or funding on project activities.
NASA calculated the project’s joint cost and schedule
confidence level—the likelihood a project will meet its cost
and schedule estimates—as greater than 70 percent, as
generally required by NASA policy.

Similar to the previous 2 years, NASA did not request
funding for PACE in its fiscal year 2020 budget request,
but the explanatory statement accompanying the 2020
Consolidated Appropriations Act stated that the agreement
included $131 million for PACE. A separate committee
report related to the Act directed NASA to include adequate
funding for PACE in the 2021 budget request, but NASA
did not request funding for PACE in its fiscal year 2021
budget request. Project officials said budget uncertainty
has made it more challenging to find vendors willing to work
with the project, which has resulted in the project receiving
only one offer in response to about half of its competitive
solicitations. Despite funding uncertainty, the project is
holding cost and

PACE's Ocean Color Instrument (OCI) passed its pre-environmental review in April, taking the mission one step closer to its January 2024 launch

OCI, PACE's primary sensor, is a highly advanced optical spectrometer that will be used to measure the properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light in finer spectral steps spanning the ultraviolet to near-infrared than previous NASA ocean color satellite sensors, extending key system ocean color data records for climate studies.

Perhaps that just means that OCI is a hyperspectral Imager.  Such an instrument would take a series of images. One axis of the image would correspond to cross-track position. The other axis would correspond to wavelength. Stacked together into a “hyperspectral data cube” it can be resliced to produce grounds maps in any “color” within its range of sensitivity or full optical spectrum of any point within the ground swath.

I designed and prototyped just such an “Ocean Color Instrument” in the late 1990’s, although it may not have gone down into the UV. It was a small part of an instrument suite that was not selected for deployment. It’s hard to imagine it as a stand-alone mission that costs nearly $1B.

Guessing it is the standing army needed to coordinates the image taking and analysis the images in addition to the technical folks over the number of years the PACE program is active take a large fraction of the total program budget.

The transport carrier containing NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) observatory spacecraft arrives at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Tuesday, Nov. 14, 2023. PACE was shipped from the agency’s Goddard Space Flight Center in Greenbelt, Maryland, and is targeted to launch on January 30, 2024, on a SpaceX Falcon 9 rocket lifting off from Space Launch Complex 40 at Cape Canaveral Space Force Station. The PACE observatory will help us better understand how the ocean and atmosphere exchange carbon dioxide, measure key atmospheric variables associated with air quality and Earth's climate, and monitor ocean health, in part by studying phytoplankton, tiny plants and algae that sustain the marine food web.

Report on Phys.org: https://phys.org/news/2023-11-nasa-climate-science-spacecraft-pace.html (https://phys.org/news/2023-11-nasa-climate-science-spacecraft-pace.html)

NASA's PACE spacecraft completed its journey Tuesday, Nov. 14, from NASA's Goddard Space Flight Center in Greenbelt, Maryland, to the Astrotech Spacecraft Operations facility near the agency's Kennedy Space Center in Florida.

Engineers and technicians arrived ahead of the spacecraft to prepare ground equipment for offloading and processing before fueling and final encapsulation.

PACE, which stands for Plankton, Aerosol, Cloud, and ocean Ecosystem, is targeted to launch aboard a SpaceX Falcon 9 rocket in early 2024, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The mission will help clarify how the ocean and atmosphere exchange carbon dioxide, improve upon NASA's 20-plus years of global satellite observations of ocean biology and atmospheric aerosols, and continue key measurements related to air quality and climate.

The PACE project is managed by NASA's Goddard Space Flight Center. The agency's Launch Services Program, based at Kennedy Space Center, is responsible for managing launch service for the PACE mission.

Which first stage will be used for this launch?
(semi-rhetorical question)

Falcon 9 first stages are now apparently cleared for use up to twenty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

1064.6 and 1065.6 are the Falcon Heavy side boosters for Europa Clipper.

1072.1 and 1086.1 are assigned as the side boosters for GOES-U.  1083.1 is reserved for Crew-8.

1073.13 and 1076.11 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are currently available for "single-stick" launches.

Available first stages, with UTC date of most recent recovery:
1060.18  Sep 24
1078.7    Dec 3
1081.4    Dec 19
1069.13  Dec 29
1076.11  Jan 3
1067.17  Jan 7
1073.13  Jan 15 (maybe)

Edit February 4: It's B1081.4, skipping over B1060.18 and B1078.7.  This is a high-profile Earth sciences mission and NASA may prefer a lower-use first stage over a higher-use first stage.

For most Falcon 9 launches, us enthusiasts do not know booster assignments before circa 24 to 48 hours before launch, when SpaceX publishes that launch's vital information on its website.

Exceptions are when the assignment is mentioned in a press briefing, or the hardware is identified during transport to the pad's HIF.

PACE Spacecraft Encapsulated in Payload Fairing

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft is now safely encapsulated in SpaceX’s Falcon 9 payload fairings.

The fairing halves protect the spacecraft from aerodynamic pressure and heating during the ascent phase of launch. Approximately three minutes after liftoff, the halves are jettisoned and return to Earth.

Upcoming milestones for PACE include payload integration to the Falcon 9 rocket ahead of the vehicle rolling out to the pad at Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

PACE will extend and improve upon NASA’s more than 20 years of global satellite observations of our living ocean, atmospheric aerosols, and clouds from its destination in a sun-synchronous, polar orbit. Its instruments will observe and measure how ocean ecosystems interact with the atmosphere in a changing climate.

The PACE project is managed by NASA’s Goddard Space Flight Center. The agency’s Launch Services Program, based at Kennedy Space Center, is responsible for managing the launch service for the PACE mission. 

Liftoff is targeted for no earlier than 1:33 a.m. EST on Tuesday, Feb. 6.

OneSpeed, do you have the ability to show the deorbit groundtrack at least up to the US - Canada border?  I saw the post-deorbit burn fuel venting from Colorado after the 31 January 2022 CSG-2 launch.  The same might be possible on this launch IF the second stage is sunlit as it crosses the US southbound.  Based upon the launch time I am skeptical but will be checking to see if it works for someone.

🚀 PACE is Go for Launch!

The Plankton, Aerosol, Cloud, ocean Ecosystem mission is proceeding toward liftoff at 1:33 am EST, Feb. 6 on a @SpaceX Falcon 9.

Use #AskNASA to submit a question to this morning's Prelaunch News Briefing which is LIVE NOW! ➡️ https://blogs.nasa.gov/pace/

Launch window is 90s long - so enough to adjust for any late breaking collision avoidance required. Obviously not long enough to avoid any weather issues. They plan to target the middle of the 90s window and leave the 2nd half (last 45s) for collision avoidance if needed.

Launch cost to NASA for this mission is about $81M.

Isn't the reported launch time to the second being in the middle from the above sentence?

Unless you know the actual launch window...to the second (start and end times), you can't determine the middle of the launch window.

The stage is set for Falcon 9 and NASA’s PACE spacecraft on the grounds of SLC-40.

Current liftoff is slated for tonight (tomorrow) at 1:33am local time although weather conditions are forecasted to deteriorate as the day passes - current PGO holds at 40%.

The launch is scheduled for 1:33:32AM EST (06:33:32 UTC) and that's the middle of the launch window.

I tried to determine the launch window based on the announced 06:33 UTC time, with the end of the window being 06:34:30 UTC.

Maybe I took it literally.

⏰Don't go to bed yet! PACE is launching in T-5 hours and you may have a unique chance to view it!

PACE will launch into a polar orbit which means the Falcon 9 will be heading south over Florida instead of the typical east trajectory over the ocean. Keep your eye on the sky! 🚀

I was under the impression that even for a polar orbit SpaceX had to dog-leg around the Miami metropolitan rather than a direct overflight.  Seems problematic.  This flight path from NASA LSP is inconsistent with the one posted previously in this thread?  Perhaps they are overgeneralizing?

It may look risky, but due to the dog-leg turn, the impact point for any failure at any time is going to be out in the ocean. It may be that with experience they now feel comfortable letting the instantaneous impact point hug closer to the coast.

Or perhaps the line is drawn incorrectly.

I agree.
Reminds me of the ISRO mission control map during a Sriharikota launch into SSO.  Does the flightpath pass over Sri Lanka or not?  The island doesn't appear on their map.

I assume no overflight, else why why dogleg at all?

Anyways it's not on-topic here; back to PACE.

I appreciate the mention/monitoring the countdown from Hangar AE.

As we mentioned on the NSF stream and as they just said on the NASA stream, the T0 moved 4 seconds into the window to 1:33:36AM EST (06:33:36 UTC). If I were to guess, this is to adjust for COLAs.
4 COLAS in the 4 seconds between launch window open and T-0.

Re: solar arrays… If they launch in the middle of the night, wont’t a sun synchronous orbit always keep it at night, so with no power most of the time?

Or will the limited sun it will get in the polar regions be enough? Most LEO seats probably spend ~60% in the sun, but should receive less than that.

Re: solar arrays… If they launch in the middle of the night, wont’t a sun synchronous orbit always keep it at night, so with no power most of the time?

It depends on equatorial crossing time. If it is at 6 am/6 pm, then it will always be in daylight. If its later in the day, half the orbit will be in daylight and half will be in night. Radar satellites typically use all daylight orbits, to get maximum power. Visible/IR Earth observation satellites don't want long shadows, so they launch later in the day.

Good question,  when I watch SSO from VSFB (way back) they launch at twilight so the solar panels always had sunlight on them.  However, the instrumentation might require darkness to perform properly.

It'll be in Earth's shadow for half its orbit, while for the other half it'll be in sunlight.

Local Solar Time = 13:00 hours
Time at the location observed under the satellite will (approximately) be 1:00 pm--doesn't include skewed time zones or daylight savings time.  Basically, equal to sundial time.

Personal reminder that the second stage propellant venting may be visible over parts of the Canadian and USA Midwest.  Clear night skies needed, and as dark as possible skies preferable.

This would be after the SEI-2 burn to de-orbit the second stage--which probably happened after spacecraft separation, on the opposite side of the world from the reentry zone in the southeastern Pacific.

Some reusability stats for this launch (PACE):

Booster B1081.4 turnaround time:
51 days 2 hours 32 minutes
(its previous mission was Starlink Group 6-34 on Dec 19, 2023 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 50.16 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-40 turnaround time:
8 days 13 hours 26 minutes
(the previous launch from this pad was Cygnus NG-20 on Jan 30, 2024 UTC).

FYI: median turnaround time for SLC-40 is currently 5.24 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet (https://docs.google.com/spreadsheets/d/1WwD3CzpKR6vNgYS3QlxoOK9WLi81fof9zRiXzGCnbwo/edit?usp=sharing) online.

P.S. The first launch attempt was planned on February 6 at 06:33 UTC, but the mission was delayed because of unfavorable weather conditions. If the launch wasn't scrubbed on February 6, the turnaround times would be:
- 49 days, 2 hours, 32 minutes for B1081.4;
- 6 days, 13 hours, 26 minutes for SLC-40.

Being downrange from a southern polar launch? 🤌

A view of the launch of PACE aboard a Falcon 9 from Florida...except 150 miles south. You can see the boostback as well as the reentry burn.

Then the rocket went right over my head.

I was under the impression that even for a polar orbit SpaceX had to dog-leg around the Miami metropolitan rather than a direct overflight.  Seems problematic.  This flight path from NASA LSP is inconsistent with the one posted previously in this thread?  Perhaps they are overgeneralizing?

Previous post from OneSpeed (https://forum.nasaspaceflight.com/index.php?topic=50059.msg2564629#msg2564629)  along with his interpretation.

From the SpaceX webcast telemetry, PACE did as LSP suggested, and overflew the most populous areas of Florida. This does not mean that the instantaneous impact point (IIP) did the same. The IIP would have been south of those areas at all times that the spacecraft was over them.

However, I could not have predicted this ground track from the NGA notices, because of the orientation of the failed boostback burn area, which implied a booster flightpath further to the East. It will be interesting to see if this launch trajectory is repeated.

Onespeed,
Check this video (posted above (https://forum.nasaspaceflight.com/index.php?topic=50059.msg2565948#msg2565948)) run at 400% (at 1:50 into the launch) indicates the engines are thrust vectoring the booster to perform the dogleg as you initially plotted from the NGA notice.  The SpaceX webcast telemetry plot screengrab you provided from the NASA feed is too far away, (that late in the launch sequence) and will not be as precise as we would have seen back in those days when SpaceX provided two video feeds, one (The NET) showed far better resolution for ground tracks. 

Don't discount your detailed effort, I believe your tracking is the correct one until otherwise refuted by a NASA PAO.

Best
Tony.

Are they correct about this Fact??  Might be the first for NASA but not for SpaceX.  Is that right?

PACE is LSP’s first launch to polar orbit from the East Coast and it’s the first for NASA since 1960. Other launches to polar orbit have been from Vandenberg Space Force Base. Check out tonight's launch trajectory!

You miss the detail that it is the first NASA LSP polar launch not the first NASA polar launch from the East Coast.

Fuel-rich: 9x

Tough night for a lot of cameras on the pad between the low temperatures and dew covering a lot of our gear.

But that doesn’t take away from how special PACE has felt as a whole - between the spacecraft itself and the incredible minds behind this mission, we are so lucky to be witnessing it all.

Godspeed, lil buddy!

I prefer the NASA Media Channel coverage.  No graphic overlays that hide what is happening and no repeating mindless scrolls that also hide what is happening.

An added benefit, no "X" that suddenly stops working.

That made me laugh, thanks Ed.  I watch it on NASA+, but I didn't make the effort to look up the stats.

Re: solar arrays… If they launch in the middle of the night, wont’t a sun synchronous orbit always keep it at night, so with no power most of the time?

It depends on equatorial crossing time. If it is at 6 am/6 pm, then it will always be in daylight.
If its later in the day, half the orbit will be in daylight and half will be in night.
Radar satellites typically use all daylight orbits, to get maximum power.
Visible/IR Earth observation satellites don't want long shadows, so they launch later in the day.

(my bolding)
To be precise, at minimum almost two thirds of that mid-day Sun synch orbit will be in sunlight, and at most about one third will be in the Earth's shadow, depending on the altitude, ascending node, season, etc.
(The Earth subtends about 136 degrees from a 500 km LEO, and 136/360~38%)
There are those portions of the orbit where the satellite is sunlit but above darkened nighttime below.  Those are the times we get to see the satellite passes.

Again, wrong number assigend - should be 2025-025A. This happens frequently since fall 2023.
