After a one-day delay due to weather, on Sunday, SpaceX and NASA conducted an apparently successful uncrewed Crew Dragon space capsule 鈥渋n-flight 鈥� high in the Earth鈥檚 atmosphere. The spacecraft and its Falcon 9 booster were 鈥渘ominal鈥� (space jargon for normal) in their performances.
NASA stated that on Friday, 鈥渢wo astronauts conducted a and mission teams completed launch day procedures for the first crewed flight test, from suit-up to launchpad operations.鈥�
Tuned-in viewers watched the whole abort test live on NASA TV and on from liftoff to splashdown. Ground and aircraft cameras, as well as a camera on Crew Dragon, provided live 鈥� and spectacular 鈥� views. SpaceX employees at SpaceX鈥檚 Hawthorne, California facility could be heard cheering loudly with each phase’s success.
The apparent successful test will undergo a comprehensive review and a thorough inspection of the recovered Crew Dragon spacecraft. This review and some remaining testing of the Mark III main parachutes must be done before assigning a launch date for the first crewed launch.
SpaceX and NASA will also be pouring over the data recovered from two anamorphic test dummies filled with sensors to measure stresses and other environmental factors experienced by the test dummies. Preliminary data shows they were subjected to a maximum 3.3 g鈥檚 followed by 2.2 g鈥檚. The term 鈥済鈥檚鈥� refers to how much gravitational force is acting on an aircraft or spacecraft as well as their human occupants.
During an in-flight abort emergency that took place, the two Soyuz crew members experienced 6.7g鈥檚 during their harrowing re-entry.
After a perfect liftoff and attaining the prescribed altitude, the Falcon 9 booster shut down its engines and the Crew Dragon capsule separated and accelerated away using its engines. The spacecraft reached a maximum speed of Mach 2.2, twice the speed of sound or approximately 1,688 miles per hour and a maximum altitude of 141,000 feet or 26.7 miles.
In April 2019 an uncrewed Crew Dragon suffered an 鈥渁nomaly鈥� just a half-second before the ground test firing of its engines was to take place. The spacecraft was destroyed. An investigation determined the cause and resulted in a successful ground test of the SuperDraco engines in November 2019.
During a televised post-test news conference NASA鈥檚 Administrator, Jim Brandenstine, hailed the in-flight abort test as, 鈥渁n amazing milestone completed, a final major flight milestone with parachute tests still to follow 鈥� by all accounts a very successful test.鈥� SpaceX founder and Chief Engineer, Elon Musk said, 鈥淕reat appreciation to NASA and the SpaceX team for making this happen and achieving a successful mission, a perfect mission; We鈥檙e fired up 鈥� this was really great.鈥�
NASA has a lot riding with SpaceX鈥檚 Crew Dragon and Boeing鈥檚 , both of which are the centerpiece of NASA鈥檚 (CCP).
CCP was initiated in 2010 to return American astronauts to Low Earth Orbit (LEO) and the International Space Station (ISS) using spacecraft built by the launched from American soil. It has been almost a decade since that last occurred, in 2011, with the last flight of space shuttle Atlantis. In 2014 NASA issued contracts to SpaceX and Boeing to begin building their respective spacecraft.
Currently humanity can only access LEO and the ISS using the Russian spacecraft. NASA currently pays Russia about $85 million a seat and has stated it will purchase more seats even when CCP is fully operational. This will help ensure at least three systems are available for humans to access LEO and ISS.
History has shown that having multiple ways to get humans into space is necessary. The faulty dependence on only one human rated spacecraft was painfully shown in the Apollo 1, Challenger and Columbia accidents which resulted in NASA human spaceflight being grounded for years.
Quite frankly, you can never have enough systems to allow access to space, as uncrewed resupply missions to the ISS were halted for months in 2015 when three separate delivery systems were grounded due to unrelated .
On Dec. 20, 2019, Boeing successfully launched its first Starliner into space for an Orbital Flight Test (OFT) that would result in followed by re-entry and touchdown. An anomaly occurred aboard the uncrewed Starliner, which prevented the successful rendezvous and docking with ISS.
The Starliner did successfully re-enter the Earth鈥檚 atmosphere and safely touchdown on land in New Mexico. It is currently unknown if Boeing will have to repeat the OFT before a crew is launched.
It was not announced when NASA would fly astronauts into space on Crew Dragon (or CST-100 Starliner).
鈥淪hort or long duration for first crewed flight? NASA鈥檚 decision to be made in the next few weeks. With an apparently successful test we now have options,鈥� Brandenstine said.
For beyond LEO NASA intends to 鈥渓and the first woman and the next man鈥� on the Moon by 2024 with its ambitious Program. This year will be a very busy year for .
Problems, delays, anomalies and yes, fatal accidents can occur with every spaceflight program. As America鈥檚 first astronaut launched into space, Alan Shepherd, famously said after hours of delays for his May 5, 1961 launch, ”fix your little problem and .”
Let鈥檚 hope that candles get lit in 2020.
