      ESA’s (European Space Agency) Ariane 6 rocket launches NASA’s CURIE CubeSat from Europe’s Spacesport, the Guiana Space Center in Kourou, French Guiana on Tuesday, July 9, 2024. Photo credit: ESA/S. Corvaja NASA launched CURIE (CubeSat Radio Interferometry Experiment) as a rideshare payload on the inaugural flight of ESA’s (European Space Agency) Ariane 6 rocket, which launched at 4 p.m. GFT on July 9 from Europe’s Spaceport, the Guiana Space Center in Kourou, in French Guiana.
      Designed by a team from the University of California, Berkeley, CURIE will use radio interferometry to study the primary drivers of space weather. 
      CubeSats are built using standardized units, with one unit, or 1U, measuring about 10 centimeters in length, width, and height. The two-satellite CURIE mission launched as a 6U before separating into two separate spacecraft, each a 3U. The spacecraft will provide two separate vantage points to measure the same radio waves coming from the Sun and other sources in the sky. 
      NASA’s CubeSat Launch Initiative selected CURIE in 2020 during the initiative’s 11th round of applications. NASA’s Launch Services Program, in collaboration with ESA, designated CURIE as one of eleven payloads supplied by space agencies, commercial companies, and universities for the first flight of ESA’s Ariane 6 rocket.

      Video: 00:02:54 On Saturday 29 June, thousands of visitors made their way to ESA’s European Centre for Space Applications and Telecommunications (ECSAT), as part of the very first ESA open day to be held in the UK. 
      ECSAT is located at the Harwell Science and Innovation Campus in Oxfordshire and the ESA open day formed part of the campus-wide Harwell open week. 
      The open day, hosted by ESA’s Magali Vaissiere Conference Centre, featured fascinating talks and activities that enabled people to experience first-hand how ESA is pushing the boundaries of exploration and using space to improve life on Earth. It also showcased the many career and learning opportunities in the space industry that are open to young people.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept depicts an asteroid drifting through space. Many such objects frequently pass Earth. To help prepare for the discovery of one with a chance of impacting our planet, NASA leads regular exercises to figure out how the international community could respond to such a threat.NASA/JPL-Caltech The fifth Planetary Defense Interagency Tabletop Exercise focused on an asteroid impact scenario designed by NASA JPL’s Center for Near Earth Object Studies.
      A large asteroid impacting Earth is highly unlikely for the foreseeable future. But because the damage from such an event could be great, NASA leads hypothetical asteroid impact “tabletop” exercises every two years with experts and decision-makers from federal and international agencies to address the many uncertainties of an impact scenario. The most recent exercise took place this past April, with a preliminary report being issued on June 20.
      Making such a scenario realistic and useful for all involved is no small task. Scientists from the Center for Near Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory in Southern California, which specializes in the tracking and orbital determination of asteroids and comets and finding out if any are hazards to Earth, have played a major role in designing these exercises since the first 11 years ago.
      “These hypothetical scenarios are complex and take significant effort to design, so our purpose is to make them useful and challenging for exercise participants and decision-makers to hone their processes and procedures to quickly come to a plan of action while addressing gaps in the planetary defense community’s knowledge,” said JPL’s Paul Chodas, the director of CNEOS.
      The Impact Scenario
      This year’s scenario: A hypothetical asteroid, possibly several hundred yards across, has been discovered, with an estimated 72% chance of impacting Earth in 14 years. Potential impact locations include heavily populated areas in North America, Southern Europe, and North Africa, but there is still a 28% chance the asteroid will miss Earth. After several months of being tracked, the asteroid moves too close to the Sun, making further observations impossible for another seven months. Decision-makers must figure out what to do.
      Explore asteroids and near-Earth objects in real-time 3D Leading the exercise was NASA’s Planetary Defense Coordination Office (PDCO), the Federal Emergency Management Agency Response Directorate, and the Department of State Office of Space Affairs. Over the course of two days in April, participants gathered at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, which hosted the event, to consider the potential national and global responses to the scenario.
      “This was a very successful tabletop exercise, with nearly 100 participants from U.S. government agencies and, for the first time, international planetary defense experts,” said Terik Daly from APL, who coordinated the exercise. “An asteroid impact would have severe national and international ramifications, so should this scenario play out for real, we’d need international collaboration.”
      Reality Informs Fiction
      In real life, CNEOS calculates the orbit of every known near-Earth object to provide assessments of future potential impact hazards in support of NASA’s planetary defense program. To make this scenario realistic, the CNEOS team simulated all the observations in the months leading up to the exercise and used orbital determination calculations to simulate the probability of impact.
      “At this point in time, the impact was likely but not yet certain, and there were significant uncertainties in the object’s size and the impact location,” said Davide Farnocchia, a navigation engineer at JPL and CNEOS, who led the design of the asteroid’s orbit. “It was interesting to see how this affected the decision-makers’ choices and how the international community might respond to a real-world threat 14 years out.”
      Options to Deflect
      Preparation, planning, and decision-making have been key focal points of all five exercises that have taken place over the past 11 years. For instance, could a reconnaissance spacecraft be sent to the asteroid to gather additional data on its orbit and better determine its size and mass? Would it also be feasible to attempt deflecting the asteroid so that it would miss Earth? The viability of this method was recently demonstrated by NASA’s Double Asteroid Redirection Test (DART), which impacted the asteroid moonlet Dimorphos on Sept. 26, 2022, slightly changing its trajectory. Other methods of deflection have also been considered during the exercises.
      But any deflection or reconnaissance mission would need many years of preparation, requiring the use of advanced observatories capable of finding hazardous asteroids as early as possible. NASA’s Near-Earth Object Surveyor, or NEO Surveyor, is one such observatory. Managed by JPL and planned for launch in late 2027, the infrared space telescope will detect light and dark asteroids, including those that orbit near the Sun. In doing so, NEO Surveyor will support PDCO’s objectives to discover any hazardous asteroids as early as possible so that there would be more time to launch a deflection mission to potential threats.
