📰Detailed Coverage
SpaceX Breaks Own Launch Pad Record
On June 28, SpaceX set a new record by launching 27 Starlink satellites just two days after a mission from the same launch pad in Cape Canaveral. This marks SpaceX’s ability to rapidly turn around and prepare its facilities for successive launches, underscoring its operational efficiency and commitment to expanding its Starlink internet constellation.
The subsequent launch from California further exemplifies SpaceX’s robust launch cadence, with the ability to support back-to-back missions from different geographical locations. These feats are made possible by significant advancements in technology and meticulous planning. For those tracking satellites, these frequent launches expand the opportunities to observe dynamic orbital changes; our web app can provide real-time updates on these new entries.

Japan’s Final H-2A Launch
Japan’s iconic H-2A rocket has embarked on its final flight, successfully delivering an Earth science satellite into orbit on June 28. This launch marks the end of a chapter for the vehicle that has been pivotal in establishing Japanese space capabilities over the past two decades.
The Earth observation satellite launched on this mission will help gather data critical for climate research and disaster monitoring. The H-2A’s retirement paves the way for newer technologies to take center stage in Japan’s space agenda, with the H3 series expected to build on its legacy. Tracking and data collection from this final mission remain accessible through various satellite observation tools.

Defense Department’s Satellite Data Program Withdrawal
The Defense Department has decided to terminate its satellite data programs that are essential for weather forecasting, effective immediately. This decision, announced recently, removes a vital source of meteorological data just as the peak hurricane season approaches.
The termination of the Defense Meteorological Satellite Program data could disrupt weather predictions and analysis. Users relying on this data, particularly forecasters and researchers, might need to look for alternative sources to fill the gap left by this policy change. Understanding the impact of these shifts could be aided by satellite tracking platforms that offer diverse data alternatives.
