With its eyes set on returning humans to the moon, NASA is inviting US-based companies to help design and develop lunar landers, reusable systems for astronauts to land on the earth’s natural satellite.
“We want to get started as quickly as possible. We are inviting industry and other potential partners to meet with us next week at NASA headquarters to discuss human lunar landers,” NASA Administrator Jim Bridenstine wrote in an op-ed at news site OZY.com on Friday.
The US space agency is planning to test new human-class landers on the moon, beginning 2024, with the goal of sending a crew to it 2028.
Through multi-phased lunar exploration partnerships, NASA is asking American companies to study the best approach to landing astronauts on the moon and start the development as quickly as possible with current and future anticipated technologies.
“Building on our model in low-Earth orbit, we’ll expand our partnerships with industry and other nations to explore the moon and advance our missions to farther destinations such as Mars, with America leading the way,” Bridenstine said in a statement.
“When we send astronauts to the moon in the next decade, it will be in a sustainable fashion,” he said. (IANS)
Two NASA astronauts – Nick Hague and Anne McClain – have successfully completed an over six hour spacewalk and replaced the ageing batteries on the International Space Station (ISS).
During the six hour, 39 minute spacewalk, Hague and McClain replaced nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for the power channel on one pair of the station’s solar arrays, NASA said in a statement on Friday.
They also installed adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries installed on the station’s starboard truss.
These new batteries provide an improved power capacity for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries.
The batteries store power generated by the station’s solar arrays to provide power to the station when the station is not in the sunlight, as it orbits the Earth during orbital night.
In addition, the astronaut duo also removed debris from outside of the station, securing a tieback for restraints on the Solar Array Blanket Box, NASA said.
McClain will again take a spacewalk on March 29 along with flight engineer Christina Koch to work on a second set of battery replacements on a different power channel in the same area of the ISS.
This would be the first-ever spacewalk with all-female spacewalkers, NASA said.
A third spacewalk on April 8 by Hague and David Saint-Jacques of the Canadian Space Agency will lay out jumper cables between the Unity module and the S0 truss, at the midpoint of the ISS’s backbone.
This work will establish a redundant path of power to the Canadian-built robotic arm, known as Canadarm2. They will also install cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.
Space station crew members have until now conducted 214 spacewalks in support of assembly and maintenance of the orbiting laboratory.
Spacewalkers have now spent a total of 55 days, 21 hours and 39 minutes working outside the station. (IANS)
