NASA
NASA has canceled an over-budget, behind-schedule mission to reveal robotic satellite servicing know-how in orbit, pulling the plug on a venture that has price $1.5 billion and doubtless would have price practically $1 billion extra to get to the launch pad.
The On-orbit Servicing, Assembly, and Manufacturing 1 mission, generally known as OSAM-1, would have grappled an getting older Landsat satellite in orbit and tried to refuel it, whereas additionally demonstrating how a robotic arm may assemble an antenna in house. The spacecraft for the OSAM-1 mission is partially constructed, however NASA introduced Friday that officers determined to cancel the venture “following an in-depth, unbiased venture overview.”
The house company cited “continued technical, price, and schedule challenges” for the choice to cancel OSAM-1.
Mission creep
The mission’s price has ballooned since NASA formally kicked off the venture in 2016. The mission’s authentic scope referred to as for simply the refueling demonstration, however in 2020, officers tacked on the in-orbit meeting goal. This concerned including a complicated piece of apparatus referred to as the Space Infrastructure Dexterous Robot (SPIDER) primarily a 16-foot-long (5-meter) robotic arm to assemble seven structural parts into a single Ka-band communications antenna.
The addition of SPIDER meant the mission would launch with three robotic arms, together with two appendages wanted to seize onto the Landsat 7 satellite in orbit for the refueling demonstration. With this modification in scope, the title of the mission modified from Restore-L to OSAM-1.
A report by NASA’s inspector basic final 12 months outlined the mission’s delays and value overruns. Since 2016, the house company has requested $808 million from Congress for Restore-L and OSAM-1. Lawmakers responded by giving NASA practically $1.5 billion to fund the event of the mission, practically double what NASA stated it needed.
Restore-L, after which OSAM-1, has all the time loved assist from Congress. The mission was managed by NASA’s Goddard Space Flight Center in Maryland. Former Sen. Barbara Mikulski (D-Maryland) was a key backer of NASA missions run out of Goddard, together with the James Webb Space Telescope. She was the highest Democrat on the Senate Appropriations Committee when Congress began funding Restore-L in late 2015.
At one time, NASA projected the Restore-L mission would price between $626 million and $753 million and could possibly be prepared for launch within the second half of 2020. That did not occur, and the mission continued going through delays and value will increase. The most up-to-date public schedule for OSAM-1 confirmed a launch date in 2026.
In 2020, after reshaping the Restore-L mission to grow to be OSAM-1, NASA formally laid out a funds for the renamed mission. At the time, NASA stated it will price $1.78 billion to design, construct, launch, and function. An unbiased overview board NASA established final 12 months to look at the OSAM-1 mission estimated the entire venture may price as a lot as $2.35 billion, in line with Jimi Russell, a NASA spokesperson.
The realities of the satellite servicing market have additionally modified since 2016. There are a number of corporations engaged on business satellite servicing applied sciences, and the satellite business has shifted away from refueling unprepared spacecraft, as OSAM-1 would have demonstrated with the Landsat 7 Earth-imaging satellite.
Instead, corporations are focusing extra on extending satellite life in different methods. Northrop Grumman has developed the Mission Extension Vehicle, which might latch on to a satellite and supply maneuvering functionality with out reducing into the client spacecraft to refuel it. Other corporations are satellites which are designed, from the beginning, with refueling ports. The US army has a need to position gas depots and tankers in orbit to recurrently service its satellites, giving them the power to repeatedly maneuver and burn propellant with out worrying about operating out of gas.
