50 Years of Walking in Space: Spacewalkings Greatest Hits

Posted on by

Wednesday is the 50th anniversary of the worlds first spacewalk, by cosmonaut Alexei Leonov. Since then, astronauts have accomplished many milestones beyond the confines of a spacecraft

Today marks 50 years since Alexei Leonov of the former Soviet Union floated beyond the bounds of his Voskhod 2 space capsule in the worlds first spacewalk. During his 10-minute extravehicular activity (EVA), Leonov changed the way humans exist in the universe. No longer were we bound to the ground of our home planet, or even the manmade grounds of our space vehicleswe could be in the universe on our own, with only the thin protection of a spacesuit between our skin and the raw expanse of the cosmos. The ability to fly outside a spacecraft was also critical for many of humankinds greatest achievements in space, such as walking on the moon, repairing the Hubble Space Telescope and other satellites in orbit, and assembling the International Space Station.

These days NASA, the Russian Federal Space Agency and even the China National Space Administration, are old pros at managing spacewalkssometimes complicated maneuvers that last hours and feature multiple astronauts. But back on March 18, 1965, Leonov was flying, literally, into unknown territory. As he told The Smithsonians Air and Space Magazine in 2005, even his family did not know he would be making the spacewalk until it happened, prompting his four-year-old daughter, watching him on TV, to wail, Please tell Daddy to get back inside. w. And the lack of atmospheric pressure out in space caused Leonovs suit to deform in unexpected ways, making it difficult for him to reenter his spacecraft and putting his life at risk. He managed, however, and racked up an important success in the space race, beating the Americans by less than three months (Ed White made the first U.S. spacewalk on June 3, 1965, from Gemini 4).

We have come a long way since then, and still have a long way to go, in our quest to live and work seamlessly in space. Below are the greatest hits of spacewalking historyyou can see a slideshow of these feats here: 50 Years of Walking Through Space [Slideshow]

The Greatest Spacewalking Feats of All Time

The First Spacewalk March 18, 1965 Soviet cosmonaut Alexi Leonov became the first person to float outside a spacecraft during a 10-minute excursion on the Voskhod 2 mission. His spacesuit deformed in the vacuum of space, forcing Leonov to vent oxygen out of his suit to squeeze himself back inside.

The First American Spacewalk June 3, 1965 NASA astronaut Edward H. White, II, doubled Leonovs time when he made the U.S.s first spacewalk less than three months later. White floated outside his Gemini 4 capsule for 21 minutes, using a zip gun that ejected pressurized oxygen to maneuver himself around in space. White enjoyed using the gun, but subsequent spacewalkers reported that it was difficult to operate, so it was rarely used after the Gemini program.

The First Untethered Spacewalk February 7, 1984 Until the space shuttle Challengers STS-41B mission, spacewalkers were tethered to their spaceships by a long cord. These tethers also limited their movements, however, and sometimes made maneuvering difficult. Astronaut Bruce McCandless II was the first to test out the Manned Maneuvering Unita type of jetpack that he wore on his back to steer himself around. Unchecked by a tether, McCandless flew 100 meters out from the shuttles cargo baythe farthest a spacewalker had ever been before.

Hubble Repair Spacewalks December 5-9, 1993 The Hubble Space Telescope was launched to much fanfare in April 1990, but soon after it became apparent that the observatorys optics were flawed. To save the $2.5 billion telescope, NASA sent seven astronauts on a rescue mission onboard the shuttle Endeavour. Four of the STS-61 crew F. Story Musgrave, Jeffrey A. Hoffman, Kathryn C. Thornton and Thomas D. Akerscompleted five spacewalks in five days to install a new primary camera and corrective optics package for the telescope. Their efforts paid offthe telescope delivered on its promise to reveal the cosmos in brand new waysand four more servicing missions followed in the coming years to upgrade the observatory, which could operate through 2020.

China's space authorities have announced plans to launch over 40 different spacecrafts into orbit in 20 separate launches this year.

One of the vessels to be launched is the ground-breaking Yuanzheng 1 - also known as the 'space bus' - which can launch 10 different satellites at once.

2013 was a massive year for China whose scientists launched 16 spacecraft to firmly establish their cosmic credentials.

In October 2003, it became only the third country in history to independently launch a manned mission into space on the Shenzhou 5.

NASA's RapidScat sees waning winds of Tropical Depression Bavi

Posted on by

IMAGE:RapidScat data showed Tropical Depression Bavi's strongest surface winds were northwest of the center at 17 m/s (38 mph/61 kph) and weaker around the rest of the storm.... view more

Tropical Cyclone Bavi weakened to a depression and NASA's RapidScat instrument measured its waning winds from space.

On March 17 the RapidScat instrument aboard the International Space Station (ISS) measured Bavi's surface winds from 01:28 to 3:01 UTC. RapidScat data showed surface winds were strongest winds in the northwestern quadrant. Sustained winds were near 17 m/s (38 mph/61 kph) and weaker around the rest of the storm.

On March 18 at 0000 UTC (March 17 at 8 p.m. EDT), the Joint Typhoon Warning Center noted that Bavi's maximum sustained winds dropped to 25 knots 28.7 mph/46.3 kph). It was located near 15.8 north latitude and 132.8 east longitude, approximately 489 nautical miles northwest of Yap, and was moving westward at 6 knots (6.9 mph/11.1 kph).

Bavi is moving west and weakening. The Joint Typhoon Warning Center expects Bavi to dissipate sometime on March 19.

Lockheed Martin jumps into the NASA space taxi race

Littleton-based Lockheed Martin Space Systems is jumping into the entry pool to be the next selected to ferry supplies to and from the International Space Station.

The company submitted a three-part system the Jupiter reusable spacecraft, Exoliner cargo container and a long robotic arm that takes inspiration from the Space Shuttle's similar appendage to try to win a piece of the $14 billion NASA pie.

"We know how important it is to get astronauts on the ISS the supplies they need on time, every time," said Wanda Sigur, vice president of Lockheed Martin's civil space division. "Our approach is designed to deliver a large volume of critical supplies and cargo with each flight, and do so on schedule."

Here's how it works: Jupiter and Exoliner would launch on a United Launch Alliance Atlas V rocket and deliver their cargo to ISS. Jupiter would remain in orbit, leaving the old Exoliner behind on ISS.

Once another Exoliner cargo delivery arrives, Jupiter would remove the old Exoliner from ISS, and replace it with the new. The old cargo container would fall from orbit, burning up upon reentry to Earth's atmosphere.

As part of the bid for the NASA Commercial Resupply Services 2 contract, the company is positioning the configuration as a potential support for future deep space exploration think interstellar mini-marts placed throughout space, serving as prepositioned stations to provide astronauts with food, fuel and equipment.

Lockheed Martin looked to their previous designs to guide its commercial resupply contract entry. Jupiter builds on the heritage of MAVEN, currently in orbit around Mars, and asteroid explorer OSIRIS-REx, currently under construction at the company's Waterton Canyon facility.

They also looked to the cargo carrier used on ISS' current Automated Transfer Vehicle to guide the Exoliner, which would have both pressurized and unpressurized cargo capacity.

The award of the contract to Lockheed Martin would bring work to Colorado, including engineering, production and testing of the Jupiter spacecraft and Exoliner 's unpressurized cargo carrier and Mission Support Module, which carries Jupiter's refueling supply, according to company spokeswoman Allison Rakes.

UH website makes groundwater research public

Posted on by

The Hawaii Institute for Geophysics and Planetology has developed a website to make data on groundwater and geothermal resources accessible to the public.

The objective for the website is to bring together UH research with data on groundwater and geothermal resources that is collected by the Hawaii Department of Land and Natural Resources (DLNR) and Department of Health (DOH), University of Hawaii at Mnoa Geochemist Donald Thomas said.

According to Thomas, groundwater data goes back 100 years or more and is not very accessible to the public. The website formats the past and current data that is more easily accessible for people who want to learn more about geothermal resources.

Ultimately what we would really like is to have a system were people can go in and understand more about the groundwater system, Thomas said.

He added the first phase of the Hawaii Groundwater and Geothermal Resource Center (HGGRC) website is to analyze the data to see how sources of groundwater have changed over time due to climate change or urban development and how they should be managed in the future.

Both the data and information on the website have been generated by Hawaii Institute of Geophysics and Planetology scientists since 2010.

The HGGRC website provides searchable map displays that show what is to come for groundwater and geothermal energy data.

Humuula GroundwaterResearch Project

One project connected to the website, the Humuula Groundwater Research Project, focuses on researching the groundwater resources on Hawaii Island.

The projects researchers will drill two holes on the grounds of the Phakuloa Training Area (PTA), in the center of the island, to depths of 6000 to 6500 feet from the surface. The goal is to reach the point where the fresh groundwater and the oceans salt water meet and take rock core samples for future scientific study.
