Their oversized cousins, Gigantic Jets, are far more rare. Only dozens have been photographed. It is no wonder, then, that observers are still seeing new behaviors in this type of powerful "super sprite." On Oct. 2nd, photographer Frankie Lucena may have recorded the first example of a "double Gigantic Jet."
https://arstechnica.com/science/201...-cost-plus-contract-for-up-to-10-sls-rockets/On Wednesday, NASA announced that it is negotiating a contract with Boeing to purchase up to 10 SLS core stages. The news release does not mention costs—NASA and Boeing have never been transparent about costs, but certainly production and operations cost for a single SLS launch will be well north of $1 billion. It also does not mention the mechanism of the contract.
A spokesperson for the agency, Kathryn Hambleton, told Ars that terms of the contract were not finalized yet. "NASA anticipates the contract will be a hybrid of cost-plus-incentive-fee and cost-plus-award-fee, potentially transitioning to firm-fixed-price," she said. "The cost incentives are designed to reduce costs during early production to enable the lowest possible unit prices for the later fixed-price missions."
http://www.moondaily.com/reports/China_drawing_up_plan_for_manned_lunar_exploration_999.htmlChina is carrying out in-depth demonstration and long-term planning for its manned lunar exploration, and has formed an overall consensus and a preliminary plan, according to a senior space engineer.
At the 1st China Space Science Assembly held in Xiamen, east China's Fujian Province, from Oct. 25 to Oct. 28, Chen Shanguang, deputy chief designer of China's manned space program, said the future trend of manned space cause is to explore the moon, and establish a lunar base to carry out scientific research, and accumulate technology and experience for going deeper into space. "The long-term goal is to send people to Mars."
The manned lunar exploration will help improve human's understanding of the formation and evolution of the moon, as astronauts may set up facilities on the moon to obtain scientific data and samples, Chen said.
The astronauts may carry out multi-disciplinary research involving fields such as physics, chemistry, astronomy and geology, and in-situ resource utilization by taking advantage of the characteristics of the moon, such as low gravity, weak magnetic field and high vacuum. The research could promote innovation and development of basic science, he said.
Solving the scientific problems involving human survival on the moon could lay a foundation for human beings to go further into deep space, Chen added.
