In the summer of 2001, the Jet Propulsion Laboratory (JPL) requested mission concepts and proposals from industry-led teams (Boeing, Lockheed Martin, and TRW). [17] The science requirements included at least 500 grams (18 oz) of samples, rover mobility to obtain samples at least 1 kilometre (0.62 mi) from the landing spot, and drilling to obtain one sample from a depth of 2 metres (6 ft 7 in).
Unless otherwise stated, the status code is part of the HTTP standard. [1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. [2] All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two ...
The Soviet Union considered a Mars sample-return mission, Mars 5NM, in 1975 but it was cancelled due to the repeated failures of the N1 rocket that would have launched it. Another sample-return mission, Mars 5M (Mars-79), planned for 1979, was cancelled due to complexity and technical problems. [14]
Flying cheaper means flying sooner—at least a little—with Nelson projecting that the missions could begin as early as 2030 when the European return vehicle would launch, followed in 2035 by ...
At the time, NASA Administrator Bill Nelson said independent reviews estimated the project would cost between $8 billion and $11 billion and that the samples may not return until 2040, which was ...
A photomontage shows tubes containing samples from Mars, as collected by NASA's Perseverance Mars rover. The agency's Mars Sample Return Program plans to bring these samples back to study them in ...
This is a list of Simple Mail Transfer Protocol (SMTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. Unless otherwise stated, all status codes described here is part of the current SMTP standard, RFC 5321. The message phrases shown are typical, but any human-readable alternative ...
Less budget, rising costs impact Mars Sample Return An $11 billion price tag for the program would cause NASA to cannibalize other science programs and missions, Nelson said.
