Nanosail-D has sailed home, burning up in the atmosphere on September 17
The solar sail Nanosail-D has sailed home, burning up in the atmosphere on September 17.
The flight phase of the mission successfully demonstrated a deorbit capability that could potentially be used to bring down decommissioned satellites and space debris by re-entering and totally burning up in the Earth’s atmosphere. The team continues to analyze the orbital data to determine how future satellites can use this new technology.
The concept being tested appears to use a solar sail as a navigating tool for guiding defunct satellites back into the atmosphere.
The 1960s space race: The US orbits its first living animal, Enos the chimpanzee
An evening pause: Fifty years ago today the United States succeeded for the first time in placing a living animal in orbit, four years after the Soviet’s launched the dog Laika into space. On November 29, 1961 NASA orbited a chimpanzee named Enos as a dress rehearsal for John Glenn’s orbital flight, then scheduled for early in 1962. See this article for some details about Enos difficult flight.
Since the flights of Gagarin, Titov, Shepard, and Grissom earlier in 1961, the 1960s space race had seemed in abeyance as NASA geared up for its first orbital manned mission, while the Soviets were typically silent about their plans. Yet, for those like myself who were alive at that time, the suspense never abated. What would happen next? Could the U.S. beat the Russians to the Moon? Only time would tell.

More commercial space news; SpaceX is expanding its Florida operations in anticipation of a increased launch rate of Falcon 9 and Dragon capsules in the coming years.
Building Boeing’s CST-100 manned capsule, the smart way
Building Boeing’s CST-100 manned capsule, the smart way.
From pressure seals used on the international space station to rendezvous and docking sensors developed for the Pentagon’s Orbital Express experiment, Boeing is drawing heavily on heritage space and aviation programs for its proposed CST-100 commercial human spacecraft.

A preview of the new Mars unmanned rover Curiousity, set for launch on Saturday
A preview of the new Mars unmanned rover Curiousity, set for launch on Saturday. This is the part of its mission that scares me the most:
The final stages of the entry, descent and landing sequence will be especially tense as the rover, dubbed Curiosity in a student naming contest, is gently lowered to the surface on cables suspended from a rocket-powered “sky crane” making its debut flight. Too large to use airbags like those that cushioned NASA’s Pathfinder, Spirit and Opportunity rovers, Curiosity will rely instead on landing rockets positioned above the rover, avoiding the challenge of coming up with a reliable way to get a one-ton vehicle off of an elevated, possibly tilted lander. Instead, Curiosity will be set down on its six 20-inch-wide wheels, ready to roll.
If it works.
ESA tracking station loses contact with Phobos-Grunt
The ESA tracking station that had made contact with Phobos-Grunt earlier this week failed repeatedly yesterday to re-establish contact.
An update on the efforts to save Phobos-Grunt
An update on the efforts to save Phobos-Grunt.
“The first pass was successful in that the spacecraft’s radio downlink was commanded to switch on and telemetry was received,” said Wolfgang Hell, ESA’s Service Manager for Phobos–Grunt. Telemetry typically includes information on the status and health of a spacecraft’s systems. “The signals received from Phobos–Grunt were much stronger than those initially received on 22 November, in part due to having better knowledge of the spacecraft’s orbital position.”
The second pass was short, and so was used only to uplink commands – no receipt of signal was expected. However, the following three passes in the early morning of 24 November proved to be more difficult: no signal was received from Phobos–Grunt.
