NASA Mars Rover Opportunity Lifts Off
Joost Schuur writes "At 11:18 PM EDT on Monday, Opportunity, the second of 2 NASA Mars Exploration Rovers took off aboard a Boeing Delta 2 Heavy rocket after several delays and begun its 305 million mile trip to the Red Planet, where it will join its sister vehicle Spirit, which launched June 10th. Spirit and Opportunity will land on opposite sides of Mars, travelling up to 40 meters a day, and use a series of instruments to search for water, including the Rock Abrasion Tool, which will grind into rocks to give scientists a peak inside. Things are going to get crowded next January in orbit, as both NASA missions join the European Mars Express mission also launched this month and the Japanese Nozomi probe, which would finally complete its troublesome 5 year journey. Those stuck on Earth can take advantage of the closest Mars opposition in 60,000 years and watch with a telescope, or follow the images provided by the International MarsWatch 2003 group." -
Venus Probe Mission Approved by Steering Committee
Anonymous Coward writes "Though often referred to as Earth's sister planet in terms of size and mass, Venus is now a totally different planet from Earth. Its temperature is high at 470C and atmospheric pressure at 100, and besides it has the characteristic atmosphere revolving at a very high speed (super rotation) and thick sulfuric acid clouds. Wrapping itself in an aura of mystery, Venus twinkles in the sky enticingly. At the Steering Committee for Space Science meeting held on May 10, the Venus probe mission was approved as an official ISAS project. http://www.isas.ac.jp/e/new/release/2001/06_03.htm l" -
Japan Tests Reusable Rocket
HobbySpacer writes: "Japan's ISAS (Institute for Space and Aeronautical Science) is testing a sub-orbital rocketship called the Reusable Rocket Vehicle Test (RVT). A video of a recent test flight is available. (Alternate source.) According to Space News, the vertical-takeoff-vertical-landing vehicle was built on an annual budget of $400k and assisted by volunteers from the Japan Rocket Society. The highest flight so far is 25m but the priority is technology development and low-cost operations, i.e. learning to run a rocket vehicle like a jet. Gradually, the flight envelope will be expanded and later more powerful engines and lighter components will be tested." Low budgets, encouraging volunteer participants -- now that's the way to run a space program!"Like the DC-X project, the approach is a throwback to the successful X projects of the 1950s when great progress was made by progressing in small steps with small dedicated teams and modest budgets. (As with the X-15, at least 2 or 3 vehicles should be built because if you don't lose at least one during testing, you aren't pushing hard enough.) Perhaps the U.S. will return to this approach, as well, since the mega, 10 bleeding edge technologies at once, all or nothing approach of the X-33 failed miserably."
