NASA, DARPA partner with Lockheed Martin nuclear-powered spaceship

Published

Lockheed Martin, a prominent weapons manufacturer, has been chosen by a US Department of Defense agency and NASA to lead the development of a nuclear-powered spacecraft under the ambitious Demonstration Rocket for Agile Cislunar Operations (DRACO) project. 

The groundbreaking contract, valued at approximately $500 million, aims to revolutionise space exploration with the introduction of nuclear thermal propulsion (NTP) engines. 

The project envisions a faster and more efficient propulsion system, with nuclear-powered rocket engines transferring heat from a reactor to hydrogen propellant to produce thrust. This advancement holds the potential to significantly reduce transit times between destinations, a critical factor in safeguarding crew members from radiation exposure during human missions to Mars.

Kirk Shireman, Vice President of Lunar Exploration Campaigns at Lockheed Martin Space, expressed excitement about the project’s potential: “These more powerful and efficient nuclear thermal propulsion systems can provide faster transit times between destinations. Reducing transit time is vital for human missions to Mars to limit a crew’s exposure to radiation.”

Lockheed Martin will collaborate with Virginia-based BWX Technologies to create the nuclear fission reactor for the engine, while the Department of Energy will contribute high-assay low-enriched uranium (HALEU) fuel for the reactor.

The DRACO project aims to achieve the first-ever in-space demonstration of nuclear thermal propulsion. Previous attempts, such as NASA’s NERVA program in the 1960s and 70s, focused on developing nuclear-powered rocket engines for deep-space missions, but no operational flights were executed.

With safety being the top priority, Lockheed Martin emphasised that the reactor will remain inactive until the spacecraft reaches a nuclear safe orbit, ensuring the system remains benign until it reaches a safe environment. Tabitha Dodson, programme manager for the DRACO program at DARPA, further clarified, “A reactor that has never been turned on is cold and benign. You can put your hand right inside the core and touch the fuel like you would any other heavy metal.”

However, concerns about potential operational failures during launch or in space have been raised. A launch failure plunging the spacecraft into the ocean could pose risks of radioactive material dispersion. To mitigate this, BWX Technologies plans to install “poison wires and poison systems” to prevent the reactor from becoming a major hazard if it comes into contact with water.

The demonstration of the nuclear thermal rocket engine is scheduled for no later than 2027, promising exciting possibilities for faster and more efficient space travel. As Lockheed Martin spearheads the historic project, experts will closely monitor its progress, marking a significant leap towards the future of space exploration and defense.

WhatsApp is implementing a new upgrade to refine the Updates tab interface, hence boosting accessibility for status and channel updates.

WABetaInfo reports that the upgrade introduces expedited shortcuts that streamline the updating of statuses and channels. Users can now select and upload photos and videos directly from the interface, reducing the steps involved in choosing media from the gallery.

The Meta-owned messaging application has also revamped the button for generating text-based status updates and introduced a feature for recording and sharing voice status updates. This offers customers a more expedient method to disseminate text and speech updates without depending on the floating action button.

The revisions correspond with recent modifications to other tabs, ensuring a modernised interface that improves navigation and update creation. WhatsApp is modifying the floating action button to facilitate content sharing within channels.

When selecting the floating action button, users will see several options, including creating status updates, starting new channels, or sharing photos, videos, voice, and text in existing channels. This revamp integrates all content-generating options into a singular section.

The new shortcuts are anticipated to be accessible to a broader user base in the forthcoming weeks. Beta testers can currently access them in the latest WhatsApp beta for Android, version 2.24.26.13, available on the Google Play Store.

Through Chinese expertise, the arrangement, which was made possible by the Special Investment Facilitation Council (SIFC), intends to increase Pakistan’s agricultural output.

The Punjab government and China’s “AI Force Tech” company have inked a memorandum of understanding (MoU) to introduce advanced agricultural machinery during Chief Minister Maryam Nawaz’s visit to China.

Through the use of advanced robotic technology, the MoU seeks to transform Pakistan’s agricultural industry, guarantee economic growth, and boost farmers’ wealth with China’s assistance.

Through the partnership, Pakistan would also have the chance to absorb knowledge about China’s sophisticated farming methods.

In the meantime, plans have been revealed by the Federal Minister of Planning to send 1,000 agricultural experts to China to study contemporary farming methods.

A Chinese business and the Punjab government previously inked an agreement to introduce cutting-edge cancer treatment technologies to Punjab.

Maryam Nawaz signed a Memorandum of Understanding (MoU) with Hygea Medical Technologies while she was in China in order to introduce cutting-edge cancer treatment equipment and techniques to Punjab.

This equipment will make it feasible to treat cancer without the need for chemotherapy or surgery.

Following a meeting with Hygea Medical Technologies President Dr. Luo Fuliang, Maryam Nawaz said the organization has promised expert assistance for the establishment of the Nawaz Sharif Cancer Hospital.

She went on to say that the hospital will work with China to treat cancer patients utilizing the newest equipment and techniques following the agreement.

Maryam Nawaz and a high-level delegation are present. From December 8 to December 15, the chief minister will go to Beijing, Shanghai, Shenzhen, and Guangzhou.

CM Maryam Nawaz is expected to attend a number of conferences, events, and meetings with the goal of enhancing bilateral relations and looking into potential joint ventures in the areas of infrastructure development, technology, agriculture, and governance.
