The #newastronauts witnessed a test of the RS-68A rocket engine this week @nasastennis. Best of all, we got to watch it with some impressive students from @hyla_hancock
Team effort: had a chance to see the room from which @csa_asc controllers work with @NASA_Johnson flight controllers to command robotic operations on the @Space_Station
…𝘵𝘰 𝘵𝘩𝘦 𝘔𝘰𝘰𝘯 𝘢𝘯𝘥 𝘣𝘢𝘤𝘬!🌙 @VP Pence has just announced the plan for our astronauts to return to the surface of the Moon by the year 2024. And this time, we’re visiting new territory – the South Pole! Follow along as we continue our journey of space exploration.
That's a big end effector! Behind us is the Dextre manipulator, which attaches to the massive Canadarm2 above us. Excited to begin two weeks of robotics training here @csa_asc
The Western US looks even more beautiful and interesting after my initial @NASA geology training. A great day out flight training with @AstroDuke over @GrandCanyonNPS, Glen Canyon, and @ZionNPS.
Liftoff! We have a successful launch of the @SpaceX#CrewDragon beginning a new era of human spaceflight. This is the first-ever launch of a commercially-built & operated American spacecraft designed for crew. The next mission for #CrewDragon will be carrying @NASA_Astronauts.
It boggles my mind that the @MarsRovers were originally designed to last 90 days. 15 years later, what an amazing accomplishment for the @NASAJPL team.
Humanity’s greatest explorers aren’t always human.
Join us as we celebrate the achievements of @MarsRovers Opportunity at the completion of a 15 year mission: go.nasa.gov/2Sw1ara#ThanksOppy
Opportunity: NASA Rover Complete Mars Mission
Drive along with NASA’s Opportunity Mars rover and hear the voices of scientists and engineers behind the mission. Designed to run for 90 days, the exploration spanned more than 15 years (2004-2019).
0.0059 m/s^2: acceleration of Earth's center of mass due to Sun's gravity
0.0023 m/s^2: Coriolis acceleration due to ISS pitch rate of an astronaut translating at 1 m/s through @Space_Station
3.3e-05 m/s^2: acceleration of Earth's center of mass due to Moon's gravity
9.81 m/s^2: acceleration of object in freefall at Earth's surface
8.68 m/s^2: accel of @Space_Station center of mass
1.63 m/s^2: accel of object in freefall at Moon's surface
0.034 m/s^2: centripetal accel at equator (makes you slightly lighter) due to Earth's rotation
I've always wondered just how inertial (i.e. non-accelerating) various reference frames are. Yesterday I finally sat down and did the math. Some of the relative magnitudes surprised me.
Here we go -- comparing accelerations (rough values):
Congratulations, @NASAInSight and @NASAJPL! We look forward to all the knowledge the InSight Lander will provide us about Mars as we prepare astronauts for the same destination. #MarsLanding
Expeditionary skills are an important focus of #astronaut training. Recently spent two weeks backpacking in Utah while exploring canyons with this fine team of awesome people. @NASA@csa_asc@NOLSedu#NEVERSTOPexploring
The 2017 NASA Astronaut Class has passed the one-year mark in their extensive training. Check out how much they’ve accomplished since the last time we saw them.
Checking in With the 2017 Astronaut Candidate Class, Pt. 2
The 2017 NASA Astronaut Class has passed the one-year mark in their extensive training. Check out the video to see how much they’ve accomplished since the last time we saw them.
Check out pictures from today's LIVE episode of Watch This Space with @JimBridenstine and the newest class of astronaut candidates where they talked about their training experiences, hopes for future space exploration missions, and more. 📸 - flic.kr/s/aHsmsNnWhA
Hot? We’ve got quite a fan in our 14x22 wind tunnel! The 40-foot diameter fan includes nine wooden Sitka Spruce blades and is powered by a solid cyclo-converter type drive with a 12,000 HP synchronous motor. Pictured: NASA Astronaut Candidate Class of 2017
What a great time to be involved in human space exploration! Congratulations to the crews of the upcoming @NASA@Commercial_Crew missions and all those who have been working towards making this a reality! #LaunchAmerica
