Indian Space Research Organisation (ISRO) launched GSLV-F06 earlier today at 4.04 p.m. IST but at approximately 47 seconds after lift off, the rocket deviated from its path when the gimbal steering system failed and the rocket exploded several seconds later as the GSLV reached an altitude of approximately 12 km and 4.5 km down range and fell into the Bay of Bengal.


This is the third unsuccessful launch in seven launch attempts of the ISRO GSLV. The launch of GSLV-D3 on April 15, 2010 failed due to a fuel pump anomaly on its cryogenic third stage. The launch of GSLV-F02 on July 10, 2006 failed.

Space shuttle Discovery is back in the Vehicle Assembly Building

Space shuttle Discovery is back in the Vehicle Assembly Building (VAB this morning Tuesday December 22, 2010. There was a crawler problem that delayed move from Launch Pad 39A until late last night (10:48 p.m. EST).  The problem with the crawler was a sensor in the crawler level control system.

While in the Vehicle Assembly Building, the shuttle's external tank will be radiographed to look for cracks in all 108 stringers. Sensors from the recent tanking test will be removed and foam reapplied. A decision is expected next week (December 30)  by NASA project managers on a possible engineering modification to install stiffeners on 36 stringers in the external fuel tank.

Mike Moses, NASA Space Shuttle Program Launch Integration manager, said the results from the tanking test on December 17, 2010 looked good although it would take a few weeks to fully analyze them.

A launch attempt on November 5, 2010 was scrubbed a hydrogen leak was found on the Ground Umbilical Carrier Plate (GUCP) which is an attaching point between the external tank and a ventilation pipe for a  7 inch quick disconnect. Cracks in foam led to discovery of cracks in the tops of two stringers. Repairs were made. No leak at the GUCP was detected during the December 17 tanking test. The space shuttle external tank has a capacity of 535,000 gallons of liquid oxygen (LOX) and liquid hydrogen (LH2). Liquid oxygen is boiling point is 90.19 K (−297.33 °F, −182.96 °C). Liquid hydrogen boiling point is −252.87 °C (−423.17 °F, 20.28 K).

Robonaut 2 will be the First Human-like Robot in Space

Image Credit: NASA

Robonaut 2 or R2 will be the the first human-like robot in space when the Leonardo Permanent Multipurpose Module (PMM) is launched with STS-133 no earlier than 3 February 2011. R2's systems and control functions will be the first human-like robot demonstrated in near-zero gravity. Robonaut 2, was developed through a Space Act Agreement jointly by NASA and General Motors as a robotic assistant that can work along side humans, whether they are astronauts in space or workers at GM manufacturing plants on Earth. R2 will be the first human-like robot to move its head and stretch its arms in microgravity. R2 consists of a head and a torso with two arms and two hands. Each arm fully extended can apply ~89 nt or ~ 20 lbf, Each finger can apply a force of ~22.2 nt or ~5 pounds. After being unpacked, it will initially R2 will be anchored in one place in the Destiny Laboratory on the ISS for operational testing. It has been ground tested to ensure it does not emit interfering electromagnetic radiation (called EMI or electromagnetic interference) with near by electronics Its materials meet stringent flammability requirements. It has been shake tested for launch conditions. Its cooling fans are very low noise emitters and it has been tested to ensure it is not too loud and not a noise distraction for ISS crew members. It runs on DC power.


Mass: 150 kg
Materials: Nickel-plated carbon fiber and aluminum.
Height: ~ 1 m(from waist to head
Shoulder width: ~0.788 m
Arm span: ~2.44 m
Sensors: 350+, total
Processors: 38 Power PC Processors located in its stomach torso region
Power requirement: 120 Volt DC
54 Servo Motors 
External control: ISS crew or ground control initiation of autonomous tasks with pre-programmed self checks.
Cameras:

  • four visible light cameras behind its visor - two for stereo vision, plus two auxiliary 
  • infrared camera housed in mouth area for depth perception
Degrees of freedom: 42, total with
  • 3 degrees of freedom in its neck, allowing it to look left, right, up, or down 
  • 7 degrees of freedom in its arms 
  • 12 degrees of freedom in its hands 
  • 4 degrees of freedom in the thumb 
  • 3 degrees of freedom each in the index and middle fingers 
  • 1 each in the ring and pinky fingers

Once its demonstration capabilities have been proven inside the station, software upgrades and lower bodies can be added, potentially allowing Robonaut 2 to move around inside the station doing mundane tasks such as cleaning filters and vacuuming and eventually working outside the ISS.

Robonauts may one day be performing EVA tasks on the ISS or in other missions such as satellite servicing. Robonauts have a future in comet and NEO exploration such as sample surveys and mapping projects, solar system missions, or Mars and Lunar landings leading the way for humans.

Soyuz TMA-20 Docks with ISS - December 17, 2010

Soyuz spacecraft docked to the Rassvet  Module
The Soyuz TMA-20 with three person crew including NASA's Cady Coleman, Russian Dmitry Kondratyev and Italian Paolo Nespoli docked with the Rassvet module of the ISS at 20:11 UT on 17-December-2010. The docking occurred over western Africa at an altitude of 386 km. The Soyuz docking probe then retracted to allow hooks and latches to bring the spacecraft to a firm seal with the station. The three new Expedition 26 residents join station commander Scott Kelly, Alexander Kaleri and Oleg Skripochka.


The Soyuz completed a roll maneuver and a station flyaround before aligning with the docking port and energuzed its headlight headlight to illuminate the docking module. The docking was live on NASA-TV with images provided by a monochrome camera of the automatic docking. The automated docking system is a radar-based system  to maneuver towards the station for docking.
