The bureaucracy of government control is slowly fading away in space exploration, at least in the US. A series of delays, cost overruns, and imposed requirements have finally started taking its toll on the Space Launch System (SLS), the next generation NASA rocket system. Now, the space agency has finally conceded a point to the commercial launch industry. It has elected to use Space X’s Falcon Heavy to launch one of its upcoming flagship missions – Europa Clipper.Continue reading “NASA Chooses Falcon Heavy Over SLS to Launch Europa Clipper, Saving About $2 Billion”
As part of the Artemis program, NASA is gearing up to send the “first woman and next man” to the Moon by 2024. Central to this is the development of the Space Launch System (SLS), the most powerful rocket since the Saturn V that took the Apollo astronauts to the Moon, and the Orion spacecraft. But after these elements transport astronauts to Lunar orbit, they will need a lander to take them to and from the surface.
For this reason, NASA contracted a number of commercial partners to develop a Human Landing System (HLS). After much consideration, NASA announced on Friday, April 16th, that they had selected SpaceX to continue developing their concept for a lunar lander. When American astronauts return to the Moon for the first time in fifty-two years, it will be a modified version of the Starship that will bring them there.Continue reading “NASA Picks SpaceX to Land Astronauts on the Moon!”
When NASA’s Space Launch System (SLS) is fully integrated, assembled, and finished with testing, it will be the most powerful rocket since the Saturn V that carried the Apollo astronauts to the Moon. To get it there, NASA has been conducting a testing campaign known as the Green Run, an 8-step assessment that culminates in a test-firing of all four of the Core’s RS-25 engines (aka. a “Hot Fire” test).
On January 16th, NASA made its first attempt at a Green Run Hot Fire test at the Stennis Space Center’s B-2 Test Stand in Mississippi, which only lasted for about one minute. Another attempt was made on Thursday, March 18th, where all four engines fired for 8 minutes and 19 seconds. This successful fire test is a crucial milestone for the SLS and brings it one step closer to sending astronauts back to the Moon.Continue reading “This Time NASA’s SLS Hotfire Goes the Full 8 Minutes”
In November of 2021, NASA will embark on a new era of space exploration as they make the inaugural launch of the Space Launch System (SLS). When it enters service, this booster will be the most powerful rocket since the Saturn V, which took the Apollo astronauts to the Moon. This is fitting since the SLS will be the rocket returning astronauts to the Moon by 2024 (as part of Project Artemis).
To get the SLS ready for its first launch, NASA has been running the Core Stage through a series of tests designed to test all the systems and components of the heavy-launch system – collectively known as a “Green Run.” The next step in this process will be a second Green Run Hot Fire Test, where all four RS-25 engines on the SLS Core Stage will fire at once to show they can operate as part of a single integrated system.Continue reading “SLS Will be Tested Again in About 3 Weeks”
Today, at close to 04:30 PM local time (CST), NASA achieved a major milestone with the development of the Space Launch System (SLS) – the heavy launch system they will use to send astronauts back to the Moon and crewed missions to Mars. As part of a Green Run Hot Fire Test, all four RS-25 engines on the SLS Core Stage were fired at once as part of the first top-to-bottom integrated test of the stage’s systems.
This test is the last hurdle in an eight-step validation process before the Core Stage can be mated with its Solid Rocket Boosters (SRBs) and sent on its maiden voyage around the Moon (Artemis I) – which is currently scheduled to happen sometime in November of 2021.Continue reading “SLS Hot Fire Test Should Have Lasted 8 Minutes, Not 1”
In less than four years, NASA will be sending the “first woman and next man” to the Moon as part of the Artemis III mission. This will be the first time that astronauts have landed on the lunar surface since the final mission of the Apollo Program, which was Apollo 17 in 1972. After careful consideration, NASA has announced the names of the 18 astronauts that make up the Artemis Team.Continue reading “NASA Announces its Artemis Astronauts: 18 People Training to Fly to the Moon”
With the passage of the NASA Authorization Act of 2010, work began on a launch vehicle that would carry cargo and crews back to the Moon and beyond. This vehicle is known as the Space Launch System (SLS), a heavy-launch system that (once fully operational) will be the most powerful rocket in the world since the Saturn V – the venerable vehicle that took the Apollo astronauts to the Moon.
Unfortunately, the development of the SLS has suffered from multiple delays over the past few years, causing no shortage of complications. However, engineering teams at NASA’s Stennis Space Center near St. Louis, Mississippi, recently completed a Green Run of the SLS’s Core Stage, which involved testing the rocket’s critical systems in preparation for its inaugural launch by November of 2021.Continue reading “NASA is Giving the SLS a “Green Run” to Prepare it for Launch in Late 2021″
Since December of 2017, NASA has been working towards the goal of sending “the next man and first woman” to the Moon by 2024, which will be the first crewed lunar mission since the Apollo Program. As part of this mission, known as Project Artemis, NASA has been developing both the Space Launch System (SLS) and the Orion spacecraft, which will allow the astronauts to make the journey.
Originally, it was hoped that the first uncrewed flight of the SLS and Orion (Artemis I) would take place later this year. But according to recent statements by Associate Administrator Steve Jurczyk, this inaugural launch will most likely take place “mid to late” in 2021. This is the latest in a series of delays for the high-profile project, which has been making impressive progress nevertheless.Continue reading “The First Artemis Launch has Been Delayed Until Mid-to-Late 2021”
On March 26th, 2019, during the fifth meeting of the reestablished National Space Council, Vice President Mike Pence challenged NASA to land astronauts on the Moon within the next five years. This represented an order to expedite Space Policy Directive-1 signed by President Trump on December 11th, 2017, which directed NASA to take all the necessary steps to send astronauts back to the Moon.
This announcement suggested that some shake-up might be taking place within the agency to make things happen. However, it appears that this now involves the demotion of two longtime NASA heads who have dedicated much of their lives to the advancement of human space exploration. Whether or not this decision came from the White House is unclear, but it is in keeping with the direction recently issued by VP Pence.Continue reading “Two NASA Heads Demoted, Possibly as Part of a Shake-Up to Get Back to the Moon.”
A dramatic week in space launcher politics has left NASA’s Space Launch System (SLS) with a vastly reduced launch manifesto and casts doubt on the prospects of future upgrades to the massive launch vehicle.
On Monday the White House’s budget request laid out the administration’s plans for NASA’s coming years. For SLS there were three significant changes.Continue reading “SLS Rocket Promises To Do Better”
