Washington, June 29: A SpaceX Dragon spacecraft loaded with about 2,600 kgs of research and supplies, including experiments investigating cellular biology, Earth science and Artificial Intelligence (AI), lifted off on a Falcon 9 rocket on Friday from Cape Canaveral Air Force Station in Florida.

This is SpaceX's 15th cargo flight to the space station under NASA's Commercial Resupply Services contract, NASA said in a statement.

The spacecraft's occupant also included a robot named Cimon, short for Crew Interactive Mobile Companion.

The pilot study with Cimon is a technology demonstration project, and an observational study, that aims to obtain the first insights into the effects on crew support by AI, in terms of efficiency and acceptance during long-term missions in space.

Research materials flying inside Dragon's pressurised cargo area also included a cellular biology investigation (Micro-12) to understand how microgravity affects the growth, gene expression and ability of a model bacterium to transfer electrons through its cell membrane along the bacterial nanowires it produces. 

Such bacteria could be used in microbial fuel cells to make electricity from waste organic material.

An Earth science instrument called the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) will provide a new space-based measurement of how plants respond to changes in water availability. This data can help society better manage agricultural water use, the US space agency added.

Dragon is scheduled to depart the station in August and return to Earth with more than 1,724 kgs of research, hardware and crew supplies, NASA said.

Mumbai, May 5: The BJP has written to the Election Commission of India seeking action against Congress and the opposition leader, Vijay Wadettiwar, for allegedly peddling lies and defaming its Mumbai North Central nominee and ex-26/11 prosecution lawyer Ujjwal Nikam.

Wadettiwar, the leader of the opposition in the Maharashtra legislative assembly, purportedly called Nikam an "anti-national" and accused him of hiding the information that then Maharashtra ATS chief Hemant Karkare wasn't killed by Kasab's bullet during the 26/11 terror attack, but fell to a bullet of a policeman affiliated to RSS.

His allegations were based on the book "Who Killed Karkare" written by retired police officer SM Mushriff.

"As a responsible leader, the opposition leader should desist from making such comments that can help the enemy nation," Nikam said.

Terming Wadettiwar's statements as "false and not based on facts", Mumbai BJP president Ashish Shekar claimed they were aimed at defaming Ujjwal Nikam and inciting emotions.

"We have written to the Election Commission of India seeking action against Wadettiwar who is a star campaigner (of Congress) and also against the Congress party for peddling lies," he added.

Shelar further said (Ajmal) Kasab was sentenced to death for killing innocent people after following a due process of law.

Kasab was the lone terrorist who was captured alive by Mumbai Police during the 26/11 terror attack by Pakistani terrorists in which at least 166 people were killed and several others were injured.

Shelar wondered whether Shiv Sena (UBT) chief Uddhav Thackeray supported the statement made by the Congress leader.

A former special public prosecutor, Nikam had represented the state in high-profile cases like the Mumbai serial bomb blasts and the 2008 Mumbai terror attack.

He is making his political foray from Mumbai North Central seat on a BJP ticket and is pitted against city Congress chief Varsha Gaikwad.
