Had I been there, I would have unstrapped and ripped the power cord off of whatever was doing that incessant, constant, infernal beeping.I want to feel like I'm going into space, not like I'm working a submarine sonar by ear...

I guess they cannot do much damage to the mission. I assuming you cannot interact with the GNC or the access hatch in flight. They could just do damage to the payload or to each other.
Any idea why the acceleration peaks out at highish 5 Gs? I'd have imagined they'd prefer something like 3 Gs for tourist flights.

With a mass efficient capsule (no wings) and an straight up/down trajectory, they are limited in what they can do.
The booster's hover landing has nothing to do with the forces on the capsule since they separate long before that.

Lars was alluding at total performance available from the booster so it would have something to do with it. I will grant that the delta-V cost of that hover landing might be lower than any gravity loss hit if limiting ascent to say 3 Gs, but haven't done any BOTE calc myself.

Seems like a weird trade to make for me especially since they're not aiming at specially trained people for flights. 5 Gs might be more than Starliner and Dragon 2 will experience on ascent and they're going to orbit!
First Commercial Payloads Onboard New ShepardOn Dec. 12, 2017, New Shepard flew again for the seventh time. Known as Mission 7 (M7), the flight featured our next-generation booster and the first flight of Crew Capsule 2.0. While our primary objective was to progress testing this new system for human spaceflight, we also achieved an exciting milestone with suborbital research in space by sending 12 commercial, research and education payloads under full FAA license for the first time. Payloads flying on New Shepard are doing important science and research onboard the 11-minute flight to space and back. During this flight, our customers get approximately three minutes in a high-quality microgravity environment, at an apogee around 100 kilometers, making New Shepard ideal for microgravity physics, gravitational biology, technology demonstrations, and educational programs.The combination of high altitude and low-gravity exposure provides an environment for a wide range of payloads ranging from basic and applied microgravity sciences to Earth and space science. Each of these domains has the opportunity to engage users ranging from universities to corporations. The rapid timelines and low costs of flight are also increasingly attracting educators and students of all ages.Below are a few highlights of investigations that were a part of the New Shepard M7 flight:Zero-Gravity Glow Experiment (ZGGE)Purdue University & Cumberland Elementary School (West Lafayette, Indiana) in partnership with Arete STEMThe Zero-Gravity Glow Experiment, or ZGGE for short, was inspired by a second grade classroom’s question: “Can fireflies light up in space?” The payload operates by mixing the appropriate chemicals during the weightless coast period of the vehicle’s mission and observing the response with a miniature video camera.DCS Montessori Middle School (Castle Pines, Colorado)In Partnership with DreamUpThis payload was a collaboration across nearly 500 K-8 students and consisted of two parts. The first included an Arduino Nano microcontroller with a sensor package, designed and programed by the students to learn more about the environment inside the Crew Capsule. The second part contained a school-wide art project that all DCS Montessori students participated in. Upon landing, the data from the experiment will be analyzed and the art will be returned to the students and shared with the community.Cell Research Experiment in Microgravity (CRExIM)Embry-Riddle University-Daytona Beach, University of Texas Health Science Center at San Antonio & Medical University of South Carolina (Daytona Beach, Florida) in partnership with Arete STEMThe CRExIM (Cell Research Experiment In Microgravity) NanoLab was a multidisciplinary effort between students and faculty in Embry-Riddle’s Spaceflight Operations degree program and Aerospace and Mechanical Engineering departments, who partnered with other teams from the University of Texas Health Science Center at San Antonio and the Medical University of South Carolina. The experiment studied how microgravity impacts the cellular processes of T-cells, which develop from stem cells in the bone marrow and are key to immune system function.Expression of Genes in Tumor GrowthEmbry-Riddle University-Daytona Beach, Grand Canyon University & Thermo Fisher Scientific (Daytona Beach, Florida) in partnership with Arete STEMThis payload focused on studying the effect of microgravity exposure on the expression of genes that play a role in tumor growth. Two modified flasks were seeded with osteosarcoma cells. Syringes containing RNAlater for cell fixation were attached to each flask and their contents were deployed just before the onset of microgravity (in the case of the experimental control flask) and just after its completion (in the case of the experimental test flask). Now that the mission is complete, the samples will be analyzed via reverse transcription-polymerase chain reaction (RT-PCR) to determine how the expression of the genes has changed.JANUS Research PlatformJohns Hopkins University-Applied Physics Laboratory (Baltimore, Maryland)The JANUS integration and monitoring platform, about the size of a car battery, provides researchers with a look at suborbital flight conditions. While this flight deployed JANUS in the shirtsleeve environment of the New Shepard cabin, future iterations will also look at the environment outside the vehicle.Evolved Medical Microgravity Suction DeviceOrbital Medicine (Richmond, Virginia) with Purdue University (West Lafayette, Indiana), with funding from NASA’s Flight Opportunities ProgramThe Evolved Medical Microgravity Suction Device could assist in treatment of a collapsed lung where air and blood enter the pleural cavity. The payload – which included the device along with a hemothorax simulator – was constructed in collaboration with the Purdue University School of Aeronautics and Astronautics. The device is able to collect blood in microgravity, and still allows for the suction to continuously inflate the lung and allow it to heal. The payload marked Blue Origin’s first flight under NASA’s Flight Opportunities program.Our frequent flight schedule will allow you to launch your experiment multiple times to iterate on findings, improve statistics, or rapidly collect data. As human flights begin, you’ll also be able to fly with your payloads for hands-on experimentation.To learn more and fly your payload with us, please visit: https://www.blueorigin.com/payloadsGradatim Ferociter!
The 5G is during DESCENT. It has nothing to do with booster performance and trading propellant for accelration, since the capsule has separated by then.If you drop straight down into the thicker atmosphere, you will decelerate hard. That’s why I mentioned the laws of physics. Entering with a significant horizontal velocity would help, but this is a straight up/down ride.
