End of NASA coverage. Post launch conference at 15:30 UTC.

Congratulations to ULA and NASA for the successful launch! That makes it three for three!

Cool, the @NOAASatellites GOES-16 satellite caught the smoke trail from this morning's #Perseverance Mars launch from Florida!
You can see it in the middle of this video.

Liftoff!

As seen from the skies above Florida’s Space Coast, NASA’s newest Mars rover, Perseverance, begins its journey to the Red Planet, launching aboard a United Launch Alliance Atlas V rocket! #Mars2020

What an absolutely beautiful morning.

Some people involved in the launch.

Nice to see Jim’s (actually smiling!) face.

He looks younger than I expected.

There are some comms issues between Perseverance and the ground. Not sure what the implications are for the health of the spacecraft.

Right now this isn't overly concerning. Seems to be an issue with the network and noise rather than Perseverance itself. But you don't like to see it.

A European dream team for Mars
30 July 2020

European scientists will help select rocks and soil from Mars in the search for life on our planetary neighbour.

Five European researchers are part of NASA’s Mars 2020 science team to select the most promising martian samples bound for Earth.

The mission to Mars launched today for its seven-month journey to the Red Planet. Once there, the team will guide the Perseverance rover as it hunts for evidence of ancient microbial life.

The group is made up of researchers from Belgium, France, Sweden and the UK. “These top scientists from across Europe are experts on how to collect, analyse and read the history of the soil under our feet. Now they will also have to anticipate the needs and challenges of working with martian samples returned to laboratories back on Earth,” says ESA’s Mars Sample Return acting programme scientist Gerhard Kminek.

For the next three years, the team will be at the core of a wider NASA team. Mark Sephton, Professor of organic geochemistry at Imperial College London in the UK, sees it as “a fantastic opportunity to have some of the finest minds in the world come together to solve one of the biggest questions in the Solar System: was there life on Mars?”

Bring it back

Sandra Siljeström, from Sweden’s research institute RISE, dreams of having the “Bring it to me now!” feeling while remotely analysing a rock spotted on Mars at the rover landing site – the Jezero crater. The area contains sediments of an ancient river delta, where evidence of past life could be preserved if it ever existed on the planet.

Once the Perseverance rover retrieves samples of rock and soil from Mars, it will seal them in canisters and drop them on the surface to be collected by a future retrieval mission.

“The Mars 2020 mission is the first step for the ultimate martian challenge: the Mars Sample Return campaign. NASA and ESA aim to deliver the material from the martian surface to Earth by 2031,” adds Gerhard.

To bring Mars samples to Earth, three carefully timed missions are required.

NASA will deliver the ESA Sample Fetch Rover to the vicinity of the Mars 2020 landing site. The European rover will autonomously track down and collect up to 36 sample tubes deposited by Perseverance, and take them to NASA’s Mars Ascent vehicle.

It’s like Christmas morning here at SLC-41 on Cape Canaveral Air Force Station. I just unboxed this remote camera image of the Atlas V lifting off with the Mars 2020 Perseverance rover for NASA🇺🇸🚀

Jim Bridenstine’s comms excellent as ever

We had a good launch this morning, we’re right on course for Mars and signal from @NASAPersevere is strong. We are working to configure the ground stations to match the strength of the spacecraft signal. This scenario is one we’ve worked through in the past with other missions.

Edit to add:

I am healthy and on my way to Mars, but may be too loud for the antennas on Earth while I'm so close. Ground stations are working to match my signal strength so that I can communicate clearly with my team.

Launch was great. But count me as nervous about the telemetry information.

I won't be comfortable until they have it coming in.

7-month journey to Mars has begun for @NASAPersevere. Join us live at 11:30am ET for the latest updates on our #CountdownToMars in a post-launch news conference: nasa.gov/live

This 'signal too strong' stuff is really weird. DSN has 4 antennas pointed at Mars 2020. Surely they could off-point one to reduce the signal level - the antennas are quite well characterized and they should be able to get any needed degree of attenuation. Or they could try receiving with the "wrong" polarization - that should reduce the signal by 20 db or so. DSN goes to enormous trouble to make everything as efficient as possible. Making it less efficient should be easy.

This is not the first time this has been a problem. You'd think they would have a plan.
