European Probe’s Perilous Landing Will Be ‘7 hrs of Terror’

November 12, 2014 By Brian Galloway Leave a Comment

To land a probe on the surface of the comet whizzing through deep space is difficult, however, this week, the ESA (European Space Agency) stab to accomplish just that. If effective, it’ll be the first time a probe has landed on the surface of the comet. NASA Officials coping with ESA’s Rosetta mission are intending to land the robot Philae probe on Comet 67P/Churyumov-Gerasimenko’s surface on 12th November. You’ll be able to follow Philae’s historic progress LIVE webcast from ESA and NASA begin 11th November and all through Wednesday. The NASA’s representatives on Earth should be aware of once the landing went well by 11:02 a.m. EST on 12th November.

Certainly, the probe landing is a risky maneuver.

Comet 67P/C-G’s detailed mapping began in August, when Rosetta turned up moving Philae. The comet’s surface is tossed with large portions of rock and cracks, and Philae’s landing system does not have approached to maneuver at the last second.

The researchers on Earth will probably have 7 hours to find out whether a Philae’s tour to the surface was successful. NASA video has even called that block of time as ‘7 hours of terror’, a reverence to the NASA Curiosity rover’s “7 minutes of terror” video that referred to the Mars rover’s landing sequence.

“Andreas Accomazzo, Rosetta operations manager at the European Space Agency, said in a Google+ Hangout on Friday (7th November), “This comet is very, very rough. But this is what we have, and this is what we are trying to do. We have to be a bit lucky as well.”

Rosetta organizers will expend 10th November and Tuesday searching in the landing orbit and planning mother spacecraft to release Philae. Among the most popular occasions is going to be late Tuesday evening, when remotes only have 4 hrs to transmit instructions to Philae and make certain it’s all set to go.

Accomazzo said, “We have 4 hours to place them together, check to ensure they’re reliable, uplink to the spacecraft — and double-check they are OK to the spacecraft. It’s a pretty dense group of activities we must do.”

First Comet Landing

The program then requires Rosetta to release Philae Wednesday at 3:35 a.m. EST. (European Space Agency authorities on the Earth will discover whether the release was effective 28 minutes and 20 seconds later, once the signal reaches Earth).

The spaceship is simply too far for controllers to do anything but hold their collective breath because the probe makes its descent. European Space Agency mission controllers should get a signal from Philae throughout its descent at approximately 5:53 a.m. EST. Once that signal is made, Rosetta can begin beaming back science information collected by Philae coming down to the comet’s surface.

By about 11 a.m. EST, researchers ought to know if Philae arrived at the surface of the comet.

Rosetta must also make several operations to remain in touch with Philae throughout its descent, landing and post-landing activities. The European Space Agency added that both Rosetta and Philae seem to be fit to date, so that they are intending to find the best.

Alan Eustace, Google Executive Break Sound Barrier, Sets New Sky-Diving Records

October 26, 2014 By Jason Leathers 3 Comments

Google Executive, Alan Eustace, broke the sound barrier and sets the world record for the highest -altitude jump this Friday by jumping off from near the top of the stratosphere — some 135,000 feet, or 41,000 meters high, reports revealed.

The New York Times reported, Alan Eustace, 57, senior vice president of knowledge at Google rose above Roswell, New Mexico for about two hours using a balloon filled with 35,000 cubic feet of helium.

Eustace’s supersonic jump was part of a project by Paragon Space Development Corp. “Eustace hung below the balloon wearing a spacesuit along with the life-support system and the GoPro cameras. After reaching 135,908 feet, Eustace cut the cord and began a 15-min fall that reportedly hit peak speeds of more than 800 miles/hour,” Paragon Development Corporation stated.

“Ascending at about 1,000 feet per minute, Alan achieved his target altitude in about two and a half hours. He spent a short time, around a half hour, experiencing the wonders of the stratosphere before being released from the balloon. In rapid free fall, Eustace experienced a short period of near weightlessness and within 90 seconds exceeded the speed of sound,” NYT reported.

Certainly, the free-fall of Eustace into the atmosphere lasted about 5 minutes, and he deployed his parachute at around 18,000 feet “and floated gently to the ground,” the statement said.

The recovery systems for the project were produced by Paragon, designed by the engineering firm ILC Dover with assistance from several other consultants and companies.

Humans cannot survive at that altitude without special equipment, according to Paragon, which says that “besides being unable to breath, exposure to the vacuum of space will cause fluids in the body to boil.”

The space suit was similar to those used for the Apollo missions and on the International Space Station, the company revealed.

Austrian daredevil Felix Baumgartner set the previous record way back in October 2012 by jumping off 128,100 feet using a sophisticated capsule and was backed by millions of dollars in sponsorship money. Although, Eustace avoided taking support from Google because he didn’t want the jump to become a marketing event.

Eustace told the New York Times, “It was a wild, wild ride. I hugged on to the equipment module and tucked my legs and I held my heading.”
